私はそのような手順を持っていますが、それを実行したいときはいつも、変数を宣言する近くで構文エラーが発生します...誰か私が間違っていることを教えてもらえますか
質問用と回答用の 2 つのテーブルと、データをこのテーブルに移行するための Excel ファイルがあります。Excel のデータは次のようになります。
ID N TITLE
3 99500 question1
4
5 answer1
6 X answer2
7 answer3
DELIMITER $$
create Procedure proc_answermigration()
begin
DECLARE @i,@n,@q,@ind,@pt varchar default '';
DECLARE @done,@aord int default 0;
DECLARE cur cursor for select ID, N, question, from test.qustionmigration;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET @done = 1;
open cur;
read_loop: Loop
fetch cur into i,n,q;
IF done THEN
LEAVE read_loop;
END IF;
if n <> '' or n <> 'X'
then
select @ind = iq.question_id, @pt = iq.points from test.qustionmigration qm
inner join ilias.qpl_questions iq on qm.question = iq.question_text
where question = q
else
insert into qpl_a_sc
(
answer_id,
question_fi,
answertext,
points,
aorder,
tstamp
)
select (select sequence from qpl_a_sc_seq),
ind,
question,
pt,
aord,
'1342884200'
from test.qustionmigration
end if;
update qpl_a_sc_seq
set sequence = sequence + 1;
if @aord = 0 then set @aord = 1;
elseif @aord = 1 then set @aord = 2;
else set @aord = 0;
end loop;
CLOSE cur;
end$$
DELIMITER ;
私はいくつかのステートメントを修正しましたが、それでも次のような構文エラーがあります:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LOOP; close cur; end' at line 52
